Dynamat Xtreme is the ultimate in rattle suppression... I'm not going to ramble about how great it is, because the bottom line, is it WORKS... so instead here are some installation tips: Prep the metal surface of your car with a degreaser such as Fantastic, and allow it to dry. Take each sheet or Dynamat and cut it into strips... I find that cutting the sheets into strips about the width of the "Dynamat" logo (printed on the aluminum itself) makes installation much easier. Dynamat extreme is REALLY sticky, and i found that a heat gun is not even needed. Simply press the Dynamat into all the crevices you can and try to cover the entire area. This is just basic tips, but feel free to email me at AJSylvain@wideopenwest.com for more help. Also, the Dynamat Rubber Roller (sold here also) makes installation a breeze.
